G-Wizard Calculator

We do a terrible job advertising it, but most of G-Wizard Calculator is free.  Seriously.  You sign up for the 30-day free trial, and when that ends, even if you don’t purchase, most of the tabs will go right on working for you.  There’s a giant treasure trove of useful calculators, utilities, and reference information there including:

• Fancy scientific calculator with automatic unit conversions and much more.
• The ultimate productivity hack for busy people–the same ToDo list with Pomodoro timer system I use myself to get all this crazy stuff done for CNCCookbook.
• Geometry and Trig Calculators for Right Triangles, Oblique Triangles, Bolt Circles, Dovetails, Tapers, Chamfers, Drilling, Chords, True Position, Points, Turner’s Cubes
• Fits and Tolerances for ISO 286, ANSI B4.2, and DIN 7172
• Thread Database with all the dimensions, tapping drills, and more
• Drill Chart
• Fastener Database with dimensions for Socket Head and Flat Head Cap Screws
• Weights and Volumes for standard metal structural shapes as well as standard lumber sizes
• Thermal Expansi0n Calculator
• Electrical Ohms Law Calculator
• Resistor Color Codes
• CNC Servo and Stepper Motor Sizing Calculators
• G- and M-Code Quick Reference
• Hardness Quick Reference with Rockwell (A, B, C, D, 15H, 30H, 45N), Brinell (Std, Hultgren, Tungsten), Vickers, and Shore scales
• Rigidity Calculator to help figure your tool rigidity
• Chatter Calculator to figure the right spindle speed to stop chatter
• Geometric, Dimensioning, and Tolerancing Quick Reference

Phew!  I can hardly keep up with all of it myself.  I know there a lifetime subscribers who are still delighted at the new things they discover.  And we just keep adding more all the time!

I thought I’d make a quick video showing how it all works:

All of this will save you time digging through machinery’s handbook or trying to Google for it.  It’s all stuff that I use constantly and you will love having it at your fingertips.  So what are you waiting for–give the G-Wizard 30-day Trial a try:

BTW, you have the choice of buying the software outright (lifetime subscription) or subscribing.  Now I hear all the time from hobbyists who don’t think they can afford G-Wizard.  First thing is that one year is cheap–not much more than a single cutter costs.  But okay, let’s suppose you still think that’s too expensive.  The thing is, at the end of that 1 year, Feeds and Speeds keep right on working too.

What’s the catch?

The catch is that once the subscription expires, there’s a spindle power limit equal to 1 horsepower for each year you subscribe.  This is perfect for a hobbyist.   A small CNC Router may not be able to use more than a 1 horsepower cut–tiny machines just aren’t rigid enough.  That means a lifetime of Feeds and Speeds, limited to 1 HP, for just the cost of 1 year of subscription.  It’s perfect for the hobbyist trying to save.

And, if you ever get a more powerful machine, just re-subscribe to unlock the limit.  No muss, no fuss.

G-Wizard Editor

G-Wizard G-Code Editor and Simulator

Everybody who tries G-Wizard Editor loves it because it's the first G-Code software whose focus is on simplifying g-code, and it's also the first to build in Conversational CNC. With conversational CNC, you can work without using CAD. Just answer a few simple questions and GW Editor will write the g-code for you. It's for all those jobs you were thinking would be faster on a manual machine, and it's a totally free additional module you get with G-Wizard Editor.
